Document Summary
Accessory digestive organ: critical for digestion, not part of alimentary canal. Largest & heaviest internal organ in body: 1. 5kg (2. 5% body weight) Location: upper r quadrant (mostly) of abdomen, upper l quadrant (partly) of abdomen, covered by: diaphragm (superiorly) & peritoneum. Protected by ribs but at risk of being perforated by: a broken rib or xiphoid process. Functions: over 200: produces & secretes bile, receives substances absorbed by the intestines thru portal circulation, processes/stores nutrients, minerals, & glucose (glycogen) Controls when to put these into blood: detoxifies ingested toxins (alcohol/drugs, breaks down old rbcs, produce blood proteins. Anterior: anteriorly, liver into l and r loves, lobes separated by a falciform ligament. Inferiorly, falciform ligament = continuous w round ligament (ligamentum teres) Connects to umbilicus: superiorly, falciform ligament turns into coronary ligament. Superior: coronary ligament reflects superiorly onto diaphragm, triangular ligaments formed at l & r angles of coronary ligament, bare area of liver bounded by coronary ligament & triangular ligament.
